BLOCK-SHAVER AND MlTER-CUTTER.

SPECIFICATION forming part of Letters Patent No. 552,439, dated December 31, 1895.

Application filed June 20,189. Serial No. 515,13 7. (No model.)

To (0% whom it may concern:

Be it known that I, JOHN S. HOERNER, of Highland, in the county of Madison and State of Illinois, have invented a certain new and useful Improvement in Block-Shavers and Miter-Cutters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to ablock-shaver and miter-cutter for the use of printers; and, briefly stated, my invention consists in a board provided with a clamping arrangement for holding the block of wood, metal,or other substance to be operated upon; a plane so arranged on a guide-frame as to cut to only a certain depth, and in a miter-box adapted to be clamped to the base-board and held thereon in position for holdin the piece to be mitered; and my invention consists in the construction and details of construction hereinafter fully described, and pointed out in the claims.

Fig. I is a top View or plan illustrating my invention. Fig. II is a side elevation with the parts'in the position shown in Fig. I. Fig. III is a rear elevation showing the plane in position for shaving the backs of electrotypes, stereotypes, or other blocks desired to be reduced in thickness, and shown in dotted lines, the plane being in the position in which it is employed when the device is used as a chuteboard. Fig. IV is a top view or plan illustrating the device when used as a chute-board. Fig. V is a vertical section taken on line V V, Fig. I, through the clamping device. Fig. VI is a top view or plan illustrating the device when used as a miter-cutter. Fig. VII is a side elevation illustrating the miter-cutting arrangement shown in Fig. VI. Fig. VIII is a rear elevation illustrating the miter-cutting arrangement. Fig. IX is a side elevation of my improved plane. Fig. X is a bottom view of the plane. Fig. XI is a side elevation of the plane when used with a rasp or file instead of a cutter. Fig. XII is a bottom view of the plane shown in Fig. XI.

It frequently occurs that electrotypes, stereotypes, and other blocks used in printing are of varying thicknesses, and that it becomes necessary to reduce them to a uniform thickness in order to get a satisfactory impression in printing; also that the ends or sides require to be dressed to bring the edges to square faces.

It is the object of my invention to provide an efficient device by which the said cutting down or dressing may be readily accomplished and my invention has for its further object the formation of an efficient mitercutter for use in cutting miters on borderpieces, &c., such as wood or metal rules.

Referring to the drawings, 1 represents the base-board, provided at its front with a clownwardly-extending flange 2, adapted to bear against the front of a table to prevent forward movement of the baseboard 1 when the plane is moved forward in shaving the article inserted to be operated upon. The top of the base-board is provided with ribs 3 and 4, and extending crosswise of the base-board is a slot 5, allowing movement of the clamping device, to be presently described.

6 represents a movable bar, which bears upon one edge of the article (represented by A) to be operated upon and holds said article between it and the rib 3. The bar is provided with a bolt 7, passing through its center and through the slot 5, and on the lower end of this bolt is a nut 8, bearing against a washer or washers 9 on the under side of the base-board 1, and secured to the nut 8 is a handle-bar 10, extending to the side of the base-board, where it is in easy reach to be turned to tighten the nut 8 and thus clamp the bar 6 tightly to the base-board in any desired position.

IVhen a block to be operated upon is placed on the base-board against the rib 3, and the nut 8 being loosened, the bar 6 is moved up against the opposite edge of the block, and on turning the nut by the handle-bar 10 to tighten it the block is locked between the said rib S and bar 6. To more tightly lock the block against the rib 3 I provide a roughened plate 11, secured to a screw 12, passing through bar 6 and bolt 7, on the opposite end of which screw is a handle 13, by which the screw may be turned to either move the roughened plate 11 against the edge of the block or withdraw it from contact.

14 represents a guide-frame whose ends 15 straddle over the outside of the ribs 3 and 1, whichframe is open at its ends and top and bottom to receive and allow the working of a plane 16, so arranged that the extending sides 17 of the plane bear upon the two top edges of the frame when the plane has reached its downward limit, thus preventing the plane from making too deep a cut. 011 one side of the frame 1a are extensions provided for the purpose of giving a wider bearing-surface of the frame against the sides of the ribs 3 and 4; to prevent lateral play of the frame.

hen the device is to be used to sh. ve the edges of blocks, the frame let is laid upon its side on the lower portion 1 of the base-board with its ends 15 fitting against the sides of the ribs 3 and at, (see Figs. III and IV,) and when the device is used in this way the roughened plate 11 is preferably not in contact with the block being shaved, but the block is merely guided between the rib 3 and bar (3, so that it may be pressed forward by hand as the edge of the block is cut away.

18 represents a miter-box having a beveled end 18 and provided with a groove, in which a piece to be mitered (represented by B) is inserted and fed down to the plane by hand as it is cut away until the desired amount of cutting is accomplished. The miter-box is inserted between rib 3 and bar 6 and clamped in said position in the same manner as a block is inserted and held.

In Figs. IX and X, I have shown a plane provided with a cutter 1.), above which is an opening 20 that receives the shavings, which form of plane is used when the piece operated upon is of wood or other soft substance.

In Figs. XI and XII, I have shown the plane PPOXldQCI with a rasp 0r file 21 for use when the piece operated upon is of metal or other hard substance.

I claim as my invention 1. In a block shaver the combination of a base board, a clamp on. said board, guides on said board, a plane guide frame arranged to operate 011 said guides, and a plane arranged to operate in said guide frame.

2. In a block shaver, the combination of a base board, a clamp bar arranged to slide on said board, and a screw clamp arranged to operate in said clamp bar, and a plane guide frame arranged to be moved over said base board, and a plane arranged to operate in said guide frame.

3. In a block shaver the combination of a base board, a clamp on said baseboard, ribs on said base board, a plane guide frame arranged to fit over said ribs, and to be moved across the surface of said base board, and a plane arranged to operate in said guide frame, substantially as described.

4. In a block shaver, the combination of a base board, a clamp bar, a screw fitted to said clamp bar, and arranged to operate in a slot in said base board, a nut arranged to clamp said bar to the base board by its connection with said screw, a screw clamp working in 1 said bar, a plane guide frame arranged to be moved across the surface of said base board, and a plane arranged to operate in said guide frame.
